Application filed August 13, 1932. SerialNo. 628,754.

This invention relates to furnaces for treating copper, and hasparticular reference to that type of furnace embodying the subjectmatter of Patent Number 1,859,727.

In accordance with the present invention, improved means for forcingmixed air and steam into the copper Contents of the furnace whereby, oneside of the furnace may be in operation while the other side isidle'with the result that if one side, that is, the side in operation,burns out, the other side, that is, the inactive side, or side not inoperation, builds up so that first one side and then the other side ofthe furnace may be brought into 5 operation.

The present invention together with its numerous objects and advantageswill be best understood from a study of the following description takenin connection with the ac-.

companying drawings wherein:

Figure 1 is a side elevational view of theapparatus.

Figure 2 is an end elevational view thereof. Figure 3 is a longitudinalsectional View 25 through the furnace.

Figure 4 is a transverse sectional view through the furnace.

Referring more in detail to the drawings, it will be seen that there areprovided op- 0 posed pairs of relatively spaced short stand ards 5 onwhich are mounted flanged rollers 6 serving to support the furnace whichis generally designated by the reference charac ter 7.

8 provided with a filling opening 9 therein, and being also providedwith end plates 10,

11, secured to the flanged ends 12 of the shell.

8 by bolts 13. Adjacent each end of the shell 8 there is acircumferentially extending rib 14 engaging a pair of rollers 6 asshown.

At the end of the furnace adjacent to plate 11, there is provided a ringgear 15 that is r continually in mesh with a pinion 16 on a drive shaft17 suitably supported as suggested in the drawings and havingsuitableconnections with a source of power (not shown).

Suitably supported on opposite sides of r the shell 8 exteriorly of thelatter, and extending lengthwise of the shell are manifolds19 Thefurnace 7 includes a cylindricalshell- Pipe 22 is used for supplyingsteam to the manifolds 19 and 19 while pipe serves to supplyair to saidmanifolds, and in pipe 22 there is provided a valve 24 for controllmgthe supplyof steam, and in pipe 25 a valve 26 for controlling the supplyof air.

In the branches 20 are valves 20 and obviously by closingone ofthevalves 20', for example, the valve 20 connected with the branch 20leading from the manifold 19, the mixture of steam and air will bedirect ed to the manifold 19, and pass from said man fold 19 through thebranches 19a thereof intothe furnace fortreating the copper contents ofthe furnace in a manner and for a purpose apparent to those skilled inthe art. It will thus be-seen that steamcan be admitted to the furnacefrom either side thereof, so that one side of the furnace may be inoperation while the other side is idle with the result that while theside in operation burns out, the other or idle side is built up and willbe ready for use when desired.

As shown in Figure 3, the shell 8 of the V furnace is lined with arefractory material 28 to withstand the heat produced by the type.

From the foregoing it will be apparent that the copper or other materialmay be placed in the furnace through the opening 90 9 and by opening thevalves 24,25, and one ofthe valves 20, steam and air may be admitted tothe furnace from one side thereof, the steam and heat from the burner 29being used to properly treat the copper whilevthe I air is used to bringback oversteamed copper to normal condition.

hen the treatment of copper or other material has been completed, thefurnace may be dumped by rotating the shaft 17 which is 5 burner 29,which is preferably of the oil-feed 7 geared to the furnace shell 8 in amanner hereinbefore specifically stated.

Even though I have herein shown and described the preferred embodimentof the invention, it is to be understood that the invention issusceptible of further changes, modifications, and improvements comingwithin the scope of the appended claims.

I claim:

1. A metal treating apparatus of the character described comprising ahorizontally disposed cylinder provided with an opening in the topthereof, manifolds mounted on the cylinder at relatively opposite sidesthereof, each manifold having a series of spaced branches extendingtherefrom and terminating inwardly of the cylinder, steam and air pipeseach provided with a valve, a T-fitting connecting said steam and airpipes, and conduit means connecting said T-fitting With said manifoldsand including a universal joint.

2. A metal treating apparatus of the character described comprising ahorizontally disposed cylinder provided with an opening in the topthereof, manifolds mounted on the cylinder at relatively opposite sidesthereof, each manifold having a series of spaced branches extendingtherefrom and terminating inwardly of the cylinder, steam and air pipeseach provided with a valve, a T-fitting connecting said steam and airpipes, and conduit means connecting said T-fitting with said manifoldsand including a universal joint, said conduit means also including apair of valves arranged at relatively opposite sides of the universaljoint, there being one of such valves for each manifold, and a burnernozzle projecting into said cylinder and located in a plane above saidmanifolds.

In testimony whereof I afl'ix my signature.

WILLIS J. BENSON.
